Changes in v3:
Separate these two things into two different patches.
per suggestion from the previous thread:
https://lore.kernel.org/lkml/e2ad22bcba31797f38a12a488d4246a01bf0cb2e.camel@mediatek.com/
Changes in v2:
- change the variables' name to be more descriptive
- add a comment that describes the function of mtk_dp_audio_sample_arrange
- reduce indentation by doing the inverse check
- add a definition of some bits
- add support for mediatek, mt8188-edp-tx

For AUDIO_M_CODE_MULT_DIV_SEL_DP_ENC0_P0_*, add prefix 'MT8195_'.
And list all configuration for MT8188.

IMO, it's a bit weird to have SoC specific define in the generic header.
Are you sure this bit is only available for MT8188 ?

Eh, the P0_DIV2 bit is 5<<8 for MT8195, while for 8188 it's 4<<8, clearly :-)
